6 claims. (cl. zo-sa) This invention relates to a window having a sash rotatable upon an axis either vertically or horizontally disposed and primarily to means for holding and sealing the sash in a closed position.

With the advent of Widespread usage of air conditioned rooms, windows in those rooms are normally kept in closed positions. The window is preferably sealed against the passage around its sash or sashes of air -and moisture. Consequently sashes are now commonly" being mounted in the windows to rotate on an axis rather than to slide up and down in the well known manner.

Where these rotating windows are employed in multistoried buildings, a problem arises in washing the exterior :surfaces of the panes carried by the sashes. It would be .a normal reaction to rotate the window sash on its axis ,so as to bring the outside window around into inside exposure for washing, following which. the sash can be Yrotated back to its position to carry the Washed side of zthe pane into outside, weather exposure. icourse presents no problem in washing the pane.

The inside of However there is a problem of how to seal the sash `when in its normal closed position, and at the same time permit the seal to be released or broken so that the sash may be rotated for cleaning as has been indicated.

The means for holding the sash in its closed position 'and for sealing it in that position has to be such as to be practically fool proof since window' Washers are commonly hired on the piece rate basis, as so much a window, and the structure has to be simple and readily operated by changing washers, that is new nien coming onto the job from time to time, and who do no-t understand mechanical devices in general.

Also there is a problem of providing a sealing and retaining means which can be readily manufactured and assembled at a relatively low cost, and which will be exceedingly durable over a long period of time.`

The present invention has been conceived to solve the problem above set forth, and lends itself to a production wherein the primary elements may be extruded forms such as of aluminum alloys, wherein no machine work is required to t parts together other than possibly at corners where mitering might be desirable.

Moreover, the invention provides an exceedingly neat and well received appearance all in the absence of any exposed sealing, flexible or resilient members. In fact all of the resilient sealing` elements are entirely covered over when the Window is in its normally closed condition,

so that they are concealed from direct light adding to the ice Fig. 3 is a detail in vertical section on an enlarged scale on the line 3-3in Fig. l;

Fig. 4y is a detail in side elevation and partial section of a corner construction of the sash retaining members; and

Fig. 5 is a detail in horizontal section onthe line 5-5 in Fig. 4.

It is to be understood as above indicated that the sash generally designated by thenumeral- 10 may be pivoted at opposite ends or sides in vertical or horizontal planes or even in planes at .angles therebetween. In the present showing, the sash 10 is pivoted on a vertical axis. A Window frame is composed of four pieces, 4two side pieces 11 and 12, and top and bottom pieces 13 and 14. The cross-section of each of these four pieces is identical in shape and dimensions, and the four pieces are brought together into a rectangular frame by mitering the ends of those pieces as indicated in Fig. l. Referring to Figs. 2 and 3, a section through the frame 14 as embodied in those two views, `and a description of the shape of that section will be sufficient to define the shapes of the other three members 11, 12, and 13.

The member 14 is a generally U-rectangularly shaped extrusion made out of metal. It is provided with a floor 15' from which outer and inner sidesA 16 and 17 integrally extend upwardly, and downwardly extending mounting or securing feet 18 and 19 extend. The feet 18 and 19 are provided as means. for engaging with the wall framework, or to be imbedded in masonry if that type of construction is employed. Also there is a tongue 20 extending from the inside Wall 17 at a level just above the iloor 15 for the same purpose, namely for securing the frame member 14 to the building wall.

A pair of ribs 2.1 and 22 extend upwardly a slight distance above the topside of the floor 15 and extend along the entire length of the piece 14. These ribs 21 and 22 are spaced apart, and centrally receive therebetween a bearing block 23, Fig. 3, which is xed in position by any suitable means, herein shown as by a cap screw 24 extending upwardly throngh a thickened portion of the floor 1S and screW-threadedly engaging the block 23 from the underside.

The rib 22 is rabbeted from its side exposed toward the wall 17, to form a rectangular groove 25' therealong.

A friction block bracket 26 is formed with a depending leg 27 in turn carrying a foot 28 which slidably lits into the groove 25 so as to be shiftable therealong as may be desired. The bracket 26 has a bore 29 entering from a side, to receive therein a friction block 30 which is yieldingly urged to extend from the bore 219 by a spring 31. The friction block 30 extends from the bracket 26 in the direction of the inner side 17 of the frame piece 14.

The bracket 26 carries a web 32 extending toward the outer side 16 of the frame 14, and has a U-shaped foot 33 entering a groove 34 extending longitudinally of the frame member 14 nearer the upper end of the side 16. This groove 34 is formed between an inwardly extending Wall 35 spaced a distance above the floor 15, and inwardly extending guide 36 extending from the upper end of the side 16. Preferably the lower side of the foot 33 carries a rib 37 which may be sprung into a shallow slot 38 provided along the lower member 35 as indicated in Figs. 2 and 3. The foot 33 may be sprung into the groove or slot 34 by forcing the rib 37 to enter therein and `spring into the slot 38 as a means for detachably retaining the bracket 26 in a nonrocking position as it rests upon its foot 28.

A stop bar generally designated by the numeral 40 is carried by the frame member 14 slidingly between the friction block 30 and the inside face of the side member 17 of the member 14. This stop member 40 is generally rectangular in cross-section,4 and has a' bead 41 positioned to one side of the stop 40 by means of an intervening plate 41a, all integral with the stop 40. The stop 40 is preferably provided with a plurality of strips of insulating materials, herein shown as in three strips 42, 43, and 44. The strips are carried in grooves along the face of the stop 40 which is directed toward the inside of the frame side member 17, and these strips yieldingly bear against that face. As indicated, the upper and lower strips 42 and 44 are circular in cross-section whereas the intervening strip 43 is substantially wedge shaped with the smaller end directed toward the face of y the side member 17. The exact shapes of these sealing strips does not enter into the invention per se, and therefore are not further defined. The stop 40 has a short rib 45 extending along its lower edge at the bottom of the face 46 which is directed toward the friction block 30. The rib 4S serves as an extreme safety stop against removal of the stop member 40 by pulling upwardly on the bead 41.

As above indicated, this construction as dened in connection with the frame member 14 is duplicated in the other three members 11, 12, and 13. When these four members are assembled in the building wall, the sash carrying its pane of glass 39 is mounted in the frame by means of upper and lower pivot pins 47 and 48 respectively carried on the pivot axis of the sash 10 and directed toward the bearing blocks 23 and 23a, Fig. l. The pins are engaged by a split bearing, herein shown as consisting of the two members 49 and 50 in each instance in turn secured to the bearing blocks 23 and 23a. It is to be understood that the upper bearing block 23a is mounted in the frame member 13 in the same manner as has been described for the mounting of the bearing block 23 in the frame member 14.

Before proceeding further it is to be pointed out that there are a plurality of the brackets 26 located in isolated positions -along the various frame members 11, 12, 13 and 14, two being shown, although where the windows are of any size, there will be additional brackets employed. This is desirable in order to provide additional friction means for retaining the stops 40 in desired positions.

With all of the stops 40, 40a for the frame member 11, 4Gb for the frame member 13, and 40C for the frame member 12, in their positions retracted to their limit within the respective frame members, such as is indicated as an example in Fig. 2 by the dash lines, the window sash 10 is free to rotate on its pivots 47 and 48 from outside to inside and the reverse. When the sash 10 is to be retained in either position, the normal position for closure, or the reversed position when the pane is innermost of the frame members, the various stops 44) are pulled to be positioned across marginal edge portions of the top and bottom and two sides of the sash 10, such as is indicated in Figs. 1-3. The friction blocks 30 retain the stops 40 in any positions to which they may be shifted, so that positive stops are thus provided holding the sash 10 against rotation.

The ends of the stop 4017 are beveled at 45 degree angles and likewise the upper ends of the stops 40a and 40a are beveled at 45 degree angles, so that when these stops are shifted to lap over the marginal sides and top edge of the sash 10, those ends of the stops 46a, 40h, 40C will come together in 45 degree planes so that those ends are in abutment one with the other.

The stop member 40 comes between lower ends of the stops 40a and 40C in substantially the same manner. As indicated in Figs. l and 4, the stop 40C (the same thing applies to the stop 40a) extends downwardly to the utmost distance which the bottom edge 52 of the stop 4t) may travel as indicated by the dash line. The stop 46c is beveled at 45 degrees through the bead 41 and line 53 which extends downward to the end of the stop 40e in parallel relation to the bead 41. The stop 40C is 4 mortised as at 54 forming a recess preferably with a rounded end 55.

The stop 40 which is held by the frame member 14 is likewise beveled at each end through the bead 41 to its end designated by the numeral 56. From the end 56 there protrudes a flat, rounded end nose 57 having a thickness to enter the mortise 54. The same construction is employed in relation to the ends of the stop 4Gb and the upper ends of the stops 40a and 40C. The stop 40, Fig. 3, has a pin 58 extending from its face 46 between a pair of guide members 59 and 60, Fig. l, constituting the legs of `a channel member 61. The pin 58 permits the stop 40 to be raised and lowered, but prevents it from being shifted longitudinally.

Assuming that the window sash 10 is free to rotate on its pivots, all of the stops 40, 40a, 40b, and 40e would be retracted within their respective frame members 14, 11, 13 and 12. To retain the sash 10 in either one of its rotated positions, first the lower stop 40 is lifted upwardly by grasping the bead 41. Then the upper stop 40b is pulled downwardly, following which, the two side stops 40a and 40e are pulled one toward the other. The two side stops have their mortises 54 brought up to receive the noses 57 which a-utomatically positions these side stops 40a and 40C to be at right angles to the lower stop 40, and the upper ends of those side stops 40a and 46c will come against the ends of the top stop 4b and automatically position it by reason of the respective abutting beveled ends so that the inner edge portions of the stops will overlap the marginal edge portions of the sash 10, all 'in a uniform distance of area thereover. Preferably the marginal edge of the sas'h 10, the inside, is provided with a yielding sealing strip 63 entirely therearound so that the inner face 46 of the stops in each instance will yieldingly rest thereover. Also the inwardly extending rib 36 of the side 16 of the frame members in each instance will preferably carry a yielding molding 64 entirely thereacross so as to form an additional seal against the peripheral portions of the sash 1t) adjacent their outer sides when the sash 10 is in its normal position as indicated in Fig. 2. The exact mounting of the pane of glass 39 does not enter into the present invention per se, but is shown here in one suggested form wherein the sash 10 carries the two moldings 65 and 66 bearing against opposite marginal sides of the glass, and then a sealing or glazing molding 67 is sprung into position in the sash 10 all as is indicated in Fig. 2.

The sash 10 is released for rotation by pulling the side stops 40a and 40e apart one 4from the other whereupon the lower stop 40 may be pushed downwardly, and the upper stop `40h may likewise be pushed upwardly so as to free the various stops from Contact with the sash 10. As above indicated, the main purpose of providing the mortise 54 and the nose 57 in each instance is to center the lower stop 40 and thus in turn cause the other stops to come into their proper alignment by overlapping the sash 10 equal distances entirely therearound.

Any moisture collecting in the frame member 14 may drain out through a passageway 69 preferably directed downwardly through the side 16 from just over the oor 15. Y While I have herein shown and described my invention in the one particular form, it is obvious that structural changes may be made without departing from the spirit of the invention, and I therefore do not desire to be limited to that precise form beyond the limitations which may be imposed by the following claims.
